JOSEPH STUBER, OF PEORIA, ILLINOIS.

FLUE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 792,084, dated June 13, 1905.

Application filed October 31, 1903. Serial No. 179,343.

T0 all whom it may concern.-

Be it known that I, J osnrn STUBER, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented a new and useful Flue-Stopper, of which the following is a specification.

My invention relates to flue-stoppers, such as are employed for closing stovepipeopen ings in fines, and has for its objects to produce a simple inexpensive device of this character which in practice will seat and be maintained firmly and securely in the flue opening, thus effectively closing the latter, and one in which a large part of the soot that accumulates in the flue-opening will be collected by the stopper for removal therewith.

\Vith these and other objects in view the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a perspective view of a flue-stopper embodying my invention. section thereof illustrating the stopper in position in the flue-opening.

Referring to the drawings, 1 designates a caplate composed, preferably, of sheet meta and designed in practice to seat against the outer wall of the flue over the stovepipeopening for closing the latter. This plate has an inner asbestos lining or shield 1, whereby a picture or like ornamentation upon the outer face of the cap will be protected from the heat.

Connected with the cap-plate in a manner presently explained is a tubular thimble 2, composed, preferably, of sheet metal and designed in practice to enter the stovepipeopening, said thimble being provided with a pair of oppositely-disposed openings 3, formed through its side wall.

The thimble has one end seated against the inner face of the asbestos cover and is clamped to the cap-plate by a tension screw or element 4, extending centrally through the cap-plate and engaging a bridge-piece or member 5. This member comprises, preferably, a suitable len th of strap-metal extending transversely of the thimble and having reduced ends 6 seated, respectively, in the Fig. 2 is a vertical' openings 3 and projecting slightly beyond the outer wall of the thimble for engagement with the wall of the stovepipe-opening. The member 5 is provided with a central screwthreaded opening 7, engaged by the tensionscrew 4, and is angularly bent adjacent to its center and disposed with its apex outward, whereby when the screw is manipulated for placing the parts under tension the member will be actuated not onlyfor drawing the capplate tightly toward the end of the thimble, but also for forcing the ends 6 of the member into engagement with the walls of the flue opening, thus to maintain the cap-plate securely in position over said opening.

It is to be particularly noted that in the operation of my device the screw 4 and member 5 will not only serve to secure the device in the flue-opening, but also as the sole means for attaching the thimble to the capplate, and that the asbestos cover or shield 1 will be held in position and clamped near its margin to the plate by the thimble, thereby obviating the employment of cement or other adhesives for securing the cover to the adjacent face of the plate and at the same time permitting of the cover being readily removed and replaced by a new one when circumstances require. It is further to be observed that the inner end of the thimble is wholly open, thus permitting soot, ashes, or other matter which might settle and accumulate in the flue-opening to freely enter and be collected by the thimble for removal therewith.

From the foregoing it is apparent that I roduce a simple device admirably adapted for the attainment of the ends in view, it being understood that minor changes may be made therein without departing from the spirit of the invention.

Having thus described the invention,what is claimed is In a device of the class described, the combination with a cap-plate, of a protectinglining disposed upon one face thereof, a thimble seated u on the lining, a bridgepiece engaged wit the thimble and having projecting ends designed to engage with the walls of a stovepipe-opening, and a tension element connected With the plate and ad- In testimony that I claim the foregoing justably engaging the bridge-piece, and as my oWn I have hereto aflixed my signaadaptod to force the ends of the latter into ture in the presence of two Witnesses.
